I am not sure how to explain this problem so I'll try to be as descriptive as possible. Some video clips, labeled with the mpg extension, will not allow me to move forward through the clip, and often get hung up on a video frame, though continue to play the audio. It will display the length of the clip as much shorter then it actually is. In another words total time might show as 1:10, but the clip is twenty min long, and when the counter gets to 1:10, the clip will keep playing though the counter will stop. Also like I said sometimes the clip will stop at a certain video frame, though the audio will keep playing. Some mpg extension clips play fine, others dont. I have had this problem with wm 8, wm 9, and now wm 10. I have managed to fix the problem in the past and not know how, but whenever I create a fresh image of windows the problem comes back. I did not encode any of the clips I have problems with, so I dont know what was used. I have installed the latest divx and xvid codecs. Anyone encounter this problem before, or have any ideas.
